8.1 Cabling
Refer to CompactFlash specification.
8.2 Interface connector
The CompactFlash (CF) interface connector is designed to meet the connector interface specification
specified in CF specification revision 1.4.
8.3 Signal definition
For the pin assignments of the interface signals, refer to the CompactFlash specification revision 1.4.
8.4 Signal description
Refer to Table 4-2 of CompactFlash specification revision 1.4 with the following exceptions:
y In True IDE Mode -INPACK (pin 43) is used as DMARQ (DMA request) for DMA data transfers.
This signal is asserted by the device when it is ready to transfer data to or from the host.
y In True IDE Mode -REG (pin 44) is used as -DMACK (DMA acknowledge) for DMA data transfers.
This signal is used by the host in response to DMARQ to initiate DMA transfers.
